E279(1) High Aftercooler Temperature Warning The aftercooler temperature is above the trip point temperature. The code is logged. Probable Causes
Low coolant level
Quality of coolant
Air in cooling system
Radiator
Coolant leak
Faulty radiator cooling fan (if applicable)
Damaged hoses
Faulty temperature regulator
Faulty jacket water coolant pump
Aftercooler
Load on the systemRecommended Actions
Low Coolant Level
Inspect the coolant level. If necessary, add coolant.Quality of Coolant
Check the quality of the coolant. The coolant should have the following properties:
Color that is similar to new coolant
Odor that is similar to new coolant
Free from contamination
Properties that are recommended by the engine's Operation and Maintenance ManualIf the coolant does not have these properties, drain the system and flush the system. Refill the cooling system according to the engine's Operation and Maintenance Manual.Air in Cooling System
Check for air in the cooling system. Air can enter the cooling system in different ways. The following conditions cause air in the cooling system:
Filling the cooling system incorrectly
Combustion gas leakage into the cooling systemCombustion gas can get into the system through the following conditions: internal cracks, damaged cylinder head and damaged cylinder head gasket.Radiator
Check the cooling fins on the radiator for dirt and/or for debris. Remove the dirt and/or debris.
Check the cooling fins on the radiator for damage. Refer to the Systems Operation/Testing and Adjusting manual for instructions for testing and inspecting the cooling system.
Check the radiator for internal blockage. Check the temperature difference between the inlet and the outlet of the radiator. Coolant Leak
Check the cooling system for leaks.
Inspect the coolant for presence of bubbles. Faulty Engine Cooling Fan (if applicable)
Check for proper operation of the cooling fan.Damaged Hoses
Damaged hoses with leaks can normally be seen. Hoses that have no visual leaks can soften during operation. The soft areas of the hose can become kinked or crushed during operation. These areas of the hose restrict the coolant flow. Hoses can crack after a period of time. The inside of a hose can deteriorate and the loose particles of the hose can restrict the coolant flow.Faulty Temperature Regulator
A water temperature regulator that does not open or a water temperature regulator that only opens part of the way can cause overheating. A water temperature regulator that does not close enables overcooling.Faulty Jacket Water Coolant Pump
Inspect the impeller vanes at the jacket water pump for damage and/or for erosion. Repair impeller vanes and/or replace the impeller vanes.Aftercooler
A restriction of water flow through the aftercooler can cause overheating. Check for debris or deposits which restrict the free flow of water through the aftercooler.Load on the system
Check that the engine is not loaded beyond design.
